IMPROVEMENT IN BOBBINS.

@lgs rlge'hnle referat in in time Enters 33mm mit mating putt nf tlg time Be it known that I, W. H: RAMSDELL, of Lowell, county of .Middlesex, and State of Massachusetts, have invented a new and improved Method for Lubricating Bobbins; and I hereby decla-re the following to be a full and'exact description of the same, reference being had to the annexed drawings, and the lletters marked thereon.

Figure 1 represents a vertical vsection of the bobbin as placed upon theispindle when in.operation. Figure 2 isV an end View ofthe bobbin.

Figure 3 is an end view ofthe lubricating-feit. l

The bobbin A islof the usual form, chambered on the inside at G, iig. 1, having its bearings on the spindle B at'the two points F F. From these two bearings to the ends ofthe bobbin the hole is enlarged suilieiently to allow ol' a. thick piece of felt cloth to encircle the spindle between the two bearings F F and the two metallic rings E E.

The metallic rings are made of brass or other suitable material cut open, as shown Iat E, fig. 2, so as te allow it to besprung into place, to prevent thefelt D D from being 4pushed out when placing the bobbin upon the spindle.

The collar C is made of wood, and encire bobbin resting on the collar, as shown.

When placing the bobbin on the spindle, the felt should be well saturated with oil, which will last several days, saving time, labor, trouble, and oil. i

What I claim as new, and desire to secure by Letters Patent, is-

A bobbin, constructed as described, in combination with the spring-rings E, and felt or suitable absorben packing, as and for the purpose described.
